The syntax for the slice() method: array.slice(startIndex, endIndex) It takes two arguments: the starting index and the ending index (exclusive) of the section to be extracted. It is one of the many methods available for manipulating arrays in JavaScript.

Here is our example with outputs in comment section.ĭocument.write(names.slice(0,3)) //John,Mike,Roseĭocument.write(names.slice(3)) //Steve,Rabinĭocument.write(names.slice(1,3)) //Mike,Roseĭocument.write(names.slice(-3,-1)) // Rose,Steve document.write(names.The slice() method in JavaScript is used to extract a section of an array and return a new array containing the extracted elements. The second argument end is optional and if we don't specify then all elements staring from start till the end of the array will be returned. If we don't specify the start value then splice will start returning from 0 element or first element. The original array remians same after using slice() method.

Using slice we can specify were to start and by using another optional argument we can pass to tell where to end.

All elements of the array separated by commaīy using slice method we can collect a part of the array.
